Check Digit Verification of cas no
The CAS Registry Mumber 57855-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,5 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57855-22:
(7*5)+(6*7)+(5*8)+(4*5)+(3*5)+(2*2)+(1*2)=158
158 % 10 = 8
So 57855-22-8 is a valid CAS Registry Number.

Practical regio- and stereoselective azidation and amination of terminal alkenes
Ojo, Olatunji S.,Miranda, Octavio,Baumgardner, Kyle C.,Bugarin, Alejandro
, p. 9354 - 9358 (2019/01/03)
There is significant interest in developing more rapid and efficient production of nitrogen-containing allylic compounds, as widely used in various syntheses. This work reports a variety of allylic azides and allylic amines synthesized by an efficient, new one-pot protocol that employs readily available terminal alkenes as starting materials. This method is highly regio- and stereoselective, affording the linear (E)-isomer, under metal-free conditions. This process tolerates several functional groups including halogen-containing molecules; it is general for azides and amine nucleophiles; and, adducts were obtained in good yields.
